UEJ30-Self-amalgamating insulation tape
insulation tape.
The self-amalgamating property makes it void-free, electrical stable
build-up and resistant to moisture penetration. It is suitable for
insulating the termination and joint of polymeric insulated cable up
to 40.5kV.

Features
• Normal operation temperature: 90°C.
• Capable of operation at emergency overload temperature: 130°C.
• Excellent stretch, moisture, corrosion and chemical resistance.
Standard size
• 0.6mm×19mm×5000mm
• 0.6mm×25mm×5000mm
• Other sizes can be customized as requested
Applications
• Insulating for splices on power cable from 600V up to 35kV.
• Primary insulation for building stress cone on power cable from 600v up to 35kV
• Jacketing on high voltage terminations and splices.
• Moisture sealing for all electrical connections.
• Bus bar insulation and cable jacket repairing and end sealing.
